Video Doorbell 2 gaps in recording

Ring Video Doorbell 2: A person (my wife) exited the house and is recorded from 03:04:14pm through 03:27:12pm but is not recorded after that even though she was moving around on the porch and re-entered the house using the same door, she is not seen after 03:27pm. Snapshot is enabled but she does not appear in any snapshots after 03:27pm, she is not in the 03:29pm or the 03:45pm snapshot or the 03:59pm event. Trying to understand why. Ideas and suggestions welcome.
